720¢ |
| 8 |
8 x 50
= 400¢ |

6 x 70
= 420¢ |
820¢ |
$1 = 100¢
$8.20 = 820¢
Amount paid if all were caramel apples
= 14 x 50
= 700¢
Big difference between the amount paid for the caramel apples and the mini cupcakes
= 820 - 700
= 120¢
Small difference between the amount paid for the one caramel apple and one mini cupcake
= 70 - 50
= 20¢
Number of mini cupcakes
= 120 ÷ 20
= 6
